Varnish is a website accelerator platform, which caches content for faster access. It’s occasionally called an HTTP reverse proxy as well and it works between a web server and an Internet browser. When a site visitor accesses a certain web page, the content is requested by the browser, and then the web server processes this browser request and sends back the needed data. If Varnish is enabled for a specific site, it will cache the pages on the very first request and in case the visitor accesses a cached page once more, the content will be delivered by the caching platform and not by the server. The improved load speed is an end result of the considerably faster response time that the Varnish platform offers compared to any web server software. Of course, this does not mean that the visitors will keep seeing the same content again and again, since any modification on any of the pages is reflected in the content that the Varnish platform stores in its memory.
Varnish in Cloud Web Hosting
Varnish is offered as an optional upgrade with each Linux cloud web hosting and if you would like to use it, you can add it to your shared web hosting account using the Upgrades menu in your Hepsia Control Panel. There are two different things that can be upgraded – the number of instances and the memory. The first one refers to the number of the websites that you wish to use Varnish for and the second one, which is available in increments of 32 megabytes, displays the total amount of content that the platform can store at any particular time. The Hepsia Control Panel’s easy-to-use GUI will permit you to turn off or to reboot any instance, to check exhaustive system logs or to clear the platform’s cache with just click of the mouse. For optimum results, you can employ a dedicated IP address for the websites that will use the platform. With Varnish, your Internet site will load much faster, meaning more satisfied site users and prospective customers.
Varnish in Semi-dedicated Servers
All our Linux semi-dedicated servers include Varnish by default, so you can take advantage of the web accelerator and accelerate the load speed of any site that you host on our semi-dedicated servers. You will get 64 MB of memory dedicated to Varnish at no extra charge and you will be able to create an instance with no more than a few clicks of the mouse through the Hepsia Control Panel, which comes with the semi-dedicated packages. In case you need more memory, the latter is available in increments of 32 MB in the Upgrades section of the Control Panel and it will be at your disposal straight away. You can also add more instances as a separate upgrade, so you can choose if lots of content will be cached for one site or whether the memory will be utilized by multiple Internet sites. The Hepsia Control Panel will allow you to restart or to terminate any instance, to view the system log associated with it or to clear the cached files using 1-click controls. To get the most out of Varnish, you can assign a dedicated IP to the websites that will employ it.
Varnish in VPS Servers
We provide Varnish with all of the Hepsia-managed VPS servers, so in case you purchase a VPS with this hosting Control Panel, you’ll be able to take full advantage of the content caching platform at no additional fee. The Varnish platform can utilize different amounts of system memory for data caching purposes depending on the specific Virtual Private Server package that you have chosen on the order page, but nevertheless, this amount won’t be less than several hundred MB. This is quite enough to boost the overall performance of several different large-scale Internet sites, so the better website browsing speeds and the less load on the VPS server will be noticeable. The result may not be evident momentarily, since Varnish will require a certain amount of time to cache the site content that users request, but soon after you enable it, you’ll witness its full potential. This caching platform will allow you to use a lower-end Virtual Private Server and to give less money to get the exact same performance you would get with a higher-end virtual machine without Varnish.
Varnish in Dedicated Servers
All dedicated servers which are ordered with the custom Hepsia web hosting Control Panel include Varnish, which is one of the pre-installed platforms that you will get with the machine. The Varnish content caching platform can be set up and managed with no effort through the Hepsia Control Panel’s intuitive interface and, with no more than one click of the mouse, you can browse an exhaustive system log, create or reboot an instance, delete the cached files for any site and much more. Soon after you activate the Varnish platform for a given domain or subdomain, it will begin caching the pages browsed by your visitors and as soon as it has cached enough web content, you’ll observe a significantly faster site performance and a decreased load on the server. With Varnish-dedicated virtual memory starting at three gigabytes, you will be able to use the software platform for load distribution purposes even if you run a large number of websites on your machine.
